藜麦麸皮对玻璃表面水垢清洁性能的研究

Research on the cleaning performance of quinoa bran on glass surface water stains

[目的]藜麦麸皮水垢清洁剂是有效利用藜麦产业副产品藜麦麸皮的方式之一,本研究旨在探究其对玻璃表面水垢清洁性能。[方法]通过称重法和拍照记录的方式对藜麦麸皮除水垢性能进行系统研究。在单因素实验的基础上,采用正交试验方法优化藜麦麸皮对玻璃水垢的超声清洁工艺。并进一步通过原子吸收光谱法和高分辨扫描电镜分别对不同超声辅助清洗时间下,清洗液中元素变化、水垢表面形貌和元素含量进行分析。[结果]藜麦麸皮水分散液浓度为10%(按重量比),煮沸8 h,烧杯内壁水垢被彻底清洗干净。另外,同样藜麦麸皮浓度、超声辅助处理情况下:超声温度70℃,超声功率450 W时,发现仅需0.5 h超声处理,藜麦麸皮水分散液便将带水垢烧杯彻底清洗干净,使得藜麦麸皮清洗水垢时间缩短至无超声处理过程的6.25%,清洗水垢的效率得到极大提升。正交实验分析结果表明,影响藜麦麸皮清洗水垢性能的主次因素顺序为:超声温度、超声时间、超声功率、藜麦麸皮浓度。原子吸收光谱法和高分辨扫描电镜结果表明钙基水垢比镁基水垢更容易被藜麦麸皮基除垢剂清洗,并且用清洗模拟钙基和镁基水垢的难易程度进行了验证。[结论]本研究优化了藜麦麸皮超声清洁玻璃水垢的工艺条件,成功开发了一种天然的除水垢用品,为藜麦麸皮农副产物的高效利用提提供了一个新思路。

[Objective]Quinoa bran water scale cleaner is one of the effective ways to utilize quinoa by-products in the quinoa in-dustry.This study investigated its cleaning performance on glass surface water stains.[Method]The study systematically in-vestigated the descaling performance of quinoa bran using a weighing method and photographic records.Based on single-factor experiments,an orthogonal experimental design was used to optimize the ultrasonic cleaning process of quinoa bran for glass water stains.Furthermore,changes in elements in the cleaning solution,the surface morphology,and element content of the scale under different ultrasonic assisted cleaning times were analyzed using Atomic Absorption Spectroscopy(AAS)and high-resolution scanning electron microscopy(SEM).[Results]The results showed that a 10%concentration quinoa bran suspen-sion,boiled for 8 h,effectively removed the water scale from the inner wall of the beaker.Under the same quinoa bran concen-tration,with ultrasonic assistance,at a temperature of 70℃and a power of 450 W,only 0.5 hours of ultrasonic treatment was needed to completely clean the beaker with the quinoa bran suspension.This reduced the cleaning time to 6.25%of the time re-quired without ultrasonic treatment,greatly improving the efficiency of descaling.Orthogonal experimental analysis results indi-cated that the primary and secondary factors affecting the quinoa bran descaling performance were in the following order:ultra-sonic temperature,ultrasonic time,ultrasonic power,and quinoa bran concentration.The results of AAS and SEM demon-strated that calcium-based scale was easier to remove with quinoa bran based descaling agents compared to magnesium based scale.This confirmed the ease of cleaning calcium-based and magnesium-based scale in the simulation.[Conclusion]This study optimized the process conditions for quinoa bran ultrasonic cleaning of glass water scale and successfully developed a natural des-caling product,providing a new approach for the efficient utilization of quinoa bran by-products.
